President Donald Trump has yet to release an official statement on the incident. Paul Ryan, on the other hand, tweeted his condolences to the victims. And the U.S. State Department has issued a statement pledging to "assist in any way the UK authorities would find helpful." Spicer's comments were similarly brief as he went on, during the press conference, to discuss the American Health Care Act and the House investigation into the Trump campaign's ties to Russian operatives. Though, the press secretary did disclose that Trump had already spoken to U.K. Prime Minister Theresa May about the attacks via phone.

The day was already a busy one in the White House even before it received news of the violence in London. The House is set to vote on the controversial Trumpcare legislation this week. Meanwhile, new reports show that Trump's former campaign chairman, Paul Manafort, had closer ties with Russia than he had previously disclosed.

Earlier today, Trump tweeted "Big day for healthcare. Working hard!" He is expected to make an official statement on the incident in London soon. And though it is important that Spicer made a statement on the attack on behalf of the White House, it's Trump's potential statement that holds more weight, not only in the United States and the United Kingdom but also internationally. Trump's silence was loud when he neglected to comment on the murder of Srinivas Kuchibholta in Olathe, Kansas, in February and the mosque shooting in Quebec in January that left six people dead. At least one Trump has already made his thoughts on the attack clear, however. Donald Trump Jr. took to Twitter to criticize London Mayor Sadiq Khan only hours after the incident at Parliament took place.

Spicer offered assurances, via Twitter, that the White House is continuing to monitor the situation. And as the details of the attack are still developing, Spicer may very well have more to say about it during his next press briefing on March 23. Until then, everyone will be looking to Trump for a statement.
